DEVICE FOR SPINNING AND TWISTING TEXTILE FIBER.

Patented Nov. 26, 1918.

Application filed September 7, 1911, Serial No. 648,152. Renewed April 10, 1918: Serial No. 227.821.

, ing is a specification.

This invention relates to machines for spinning or twisting textile fiber and is in the nature of an improvement on the invention set forth in my co-pending application for United States Letters Patent Serial No. 595,187, which was characterized by a reciprocating yarn-engaging cap slidingly mounted on the spindle member by which it was rotated.

One of the features of the present invention consists in an entirely new construction of the traverse or builder rail, whereby the entire rail is located behind the spindles so that it does not obstruct in any way access to the spinning members. Another feature of the invention consists in the utilization of the movable dofling rod or bar by which the yarn is held in proper position to facilitate the dofling operation. Further features of improvement reside in the construction of the spinning cap and also in the construction of the supporting wheel upon which-the cap pivots during the operation of spinning. A new arrangement and construction of the separator mechanism is also a feature of the present invention.

In the accompanying drawings I have illustrated the preferred modes of embodying the principles of this invention.

Fig. 12 is a plan view of a portion of the builder or traverse rail showing also the arrangement of the separators.

I have shown the invention applied to a common type of spinning frame which is, however, modified as will be hereinafter pointed out to meet special conditions and obtain certain desired advantages. The vertical end frames a, the roller beam 5 and the spindle supporting rail 0, may be of the usual construction common in or suitable to spinning frames or cap frames. The threadboard 6 and the eye-blocks b .are also of the usual construction but where the .rail is given a long traverse to build a long bobbin as high as possible, I prefer to set the threadeye I)? somewhat in advance of the central axis of the spindle, for reasons to-be hereinafter explained.

The traverse or builder rail instead of be ing a flat rail with spindle holes bored therein at regular intervals through which the spindles pass, is made in the form of a hollow rail or tube cl, whose interior forms an oil reservoir which may be conveniently filled'thrbugh a short oil tube d.. At regular intervals, according to the space separating the spindles, the top face of the rail 01 is provided with a series of openings or holes to receive the bolsters e which form the bearing supports for the rotary pivot wheels f which support the cap 9. This bearing bolster 6 may be of any suitable construction to form a selflubricated bearing for the journal or supporting pin 7" of-the pivot wheel. As best shown in 8 the bolster parts are provided with holes communicating with the interior reserv ir formed in the rail 01 to permit the flow f oil to the interior of the bolster in order to keep the journal or step bearing well lubricated.

The cap 9 is preferably funnel-shaped or cup-shaped and has inside of its upper end a bushing or coupling member g which fits ea ily into the upper end of the cap but is separated therefrom by an annular piece of textile fiber tape 9 or other material suitable to minimize the transmission of vibration from the coupling member to the cap. I prefer to connect this coupling member or sleeve 9' with the cap by means of a pin or in the bobbin or spindle member h.

ceive' it, one end of said ring being bent inwardly to pass through the cap and enter a hole formed in the .exterior of the coupling member or sleeve as shown in Fig. 5. The

coupling member itself'is preferably provide d on the inside with a spline or key to engage a vertical groove or ke'yway fori ned his key instead of being made integral may be made in the form of a circular sheet metal spring g which is made of a size to be forced inside of the boreof the sleeve 9 where itexpands into an annular groove adapted to receive and retain the key ring 9*. To reduce the ballooning of the revolving yarn and to prevent its kinking, I provide the lower portion of the cap 9 with an annular projecting flange 9 adapted to engage. the revolving yarn as indicated in Figs. 2,. and 6 to hold it away from the body portion of the cap.

I prefer to make the lower yarn-engaging edge of the cap. of somewhat smaller diameter' than the largest diameter of the body portion and in order to make the cap of variable-length, according to the length of the chase of the cap, I make this narrower lower portion in the form of a separate an-. nularmember 9 formed with an annular shoulder or offset and having also an upwardly extending flange g which is slotted to make it compressible in order that it may be forced into firm engagement with the interior of the vertical lower portion 9 of the cap. As best shown in the enlarged view Fig. 8, the flange g? is a separate piece shrunk on to the exterior of the cap, while the upturned flange or annular lip g of the lower removable portion is formed with a slight bead g engaging a. shallow annular depression formed in the corresponding portion of the interior of the cap.

The form and relative arrangement of the pivot member or bearing wheel is susceptible of suitable variation. In Figs. 8, 8 and 9,

I have shown the pivot member f comprisin an u per disk i which may be of wo' meta or compressed fiber and a lower disk 7 which may be of any similar material and an interposed disk f of relatively yielding material such as felt, cloth, or the like. These three layers or disks are held together by upper and lower metallic flanges f, i which are provided with oppositely extending tubular members or flanges having screwthreaded engagement-with each other, each flange being provided with spanner holes or equivalent device to' enable them to be screwed tightly together in order to pinch the interposed disks firmly together; In the central tubular portion of the wheel is mounted the bearing pin or journal which has the enlarged'head f to give it adequate supporting (engagement with the metal clamping members which hold the parts together. The bolster f" carries an interior perforated bearin tube or box f whose periphery is vertlcally fluted to facilitate the flow of oil. The peripheral portion of the disk f is sometimes fluted or-grooved as construction, in which the cap '9 is ro-v vided with a sli htly dished flange 9 w ich is convex on its ower side, while the inserted removable lower extension member 9 mstead of being formed w1th an annular stop or shoulder, 1s curved inward. In this case the pivot wheel comprises only two disks, namely, an upper disk f, which may be of wood, fiber, metal or other suitable material, andan under disk 7? preferably made of felt, cloth or other shock-absorbing material. The upper disk which engages and supports the flange g .is preferably provided with comparatively deep radial notches, as indi-. cated in Figs. 6 and 5*, while the outside periphery, except for the rounded contour at the upper edge, is cylindrical so as to afford a lateral support to repel the opposite portion of the cap. The central portion of the disk f is recessed to form a seat-for the head of the pivot pin or journal 7.

It will be noticed that in both forms of pivot wheel and cap, the yarn is deflected from the normal course that it would assume in passing from the outside of the'spreading flange to the extreme lower edge of the cap and in such a way as to press it frictionally against the intervening portion of the pivot wheel. This frictional engagement with the pivot wheel is further augmented by notching either the upper or the lower yarn-engaging disk. These notches perform a two-fold function in that they serve in addition to the friction of the yarn against the wheel, to cause the yarn to travel at the same rate of speed as the periphery of the Wheel. As the wheel is driven by its frictional engagement with the cap and as there is a substantial amount of slip in this engagement, the wheel rotates at a slower peripheral speed than does the cap and thus serves to act as a drag to'retard the speed tion I an advantageously dispense with the annular controller shown in my former application above mentioned.

According to the usual practice in ring and traveler spinning, as the builder rail ascends to higher levels, it acts to shorten the length of the ballooning portion of the yarn, thus diminishing the tension of the yarn at the top portion of the bobbin. To avoid this variation in tension, I provide means for lifting the thread-eye progressively as the bottom edge of the cap approaches the upper part of the spindle member 0.. This may be easily accomplished by securing to the builder rail d an upwardly extending'bracket d arranged in position to engage some portion of the thread-board,

such asthe lifting handle 5 usually provided. As shown in Fig. I 11 the bracket al may be slotted in its lower end to receive the retaining screws so as'to render it adjustable. The thread-eyes may be set to project slightly in front of the central axis of the spindle member so that as the threadboard swings up, the resulting offset of the thread-eye relative to the s indle is divided equally in front of and be ind the spindle instead of all being to the rearward of the spindle.

In some cases it may be desired to use separators to keep the ballooning yarn of adjacent spindles from lashing together and breaking down ends. In such case the rail d is formed with a plurality of forward pivotally secured thereto in such a way that while all may be thrown out of operative position together or moved into operative position together, each one is nevertheless capable of independent movement from the operative position. This may be accomplished in any suitable way as by providing a series of pins or projections i normally engaging lateral notches formed in the end faces of the hubs 7?, the hubs being normally pressed into interlocking engagement with said pins or projections by means of springs z' which permit each. member to be swung into or out of locking engagement with its pin. It will be noticed that with this constructionthe separator blades may be dropped .down in front of and below the traverse. rail even when the rail is at its highest position without lowering the rail. It will be understood thatthe rail is given its traverse in the usual manner by means of the usual lifting rods d.

In the *dofiing operation on ring frames, it is'the usual practice to lower the ring rail or traverse rail before removing the full bobbin. '-In this operation the dofler in the act of removing the full bobbin, drawsthe free yarn around the spindle and then places a new bobbin on the spindle so as to pinch the yarn inside the bobbin against the spindle, after which the free portion of the yarn next to the full bobbin is broken. In a ring frame the engagement of the traveler serves to carry the free portion of the yarn down as the rail descends but. of course applicants cap cannot descend in thismanner over the full bobbin.v Uonsequently, he has devised a special doffing means for carrying down the yarn toward the base of the spindle preparatory to. the dofiing operation.

A simple form of the invention is shown in Figs. 1, 2 and 10. In this case each vertical sunnort or samson of the frame is provided with forwardly projecting brackets a .which carry longitudinal swivel pins m which are perforated transversely of their axes to receive the ends of a long looped wire rod or bail m. This bail obviously has a sliding engagement through the swivel pins m and can be swung from its lower position up over the tops of the spindles and dropped to the position indicated in Fig. 10. If desired, the bracket (1 may be provided with an additional finger 61 to form a guide and rest or support for the doffer wire to hold it in proper position and also out of contact with the pivot wheels. The combined swivel and sliding engage- :ment of the bail m permits the above described action to be readily performed and of course carries down the bight of the free portion of the yarn between the spindle and the thread-eye to thelower portion or base of the spindle, as indicated in Fig. 10. After the dofi'er member has been swung into this position and the rail lowered, the operation of doiiing is precisely the same as commonly practised in traveler ring frames. The dofler member may for convenience be provided with adjustable stops m which prevent the wire from dropping below a predetermined position when it is lifted for dofling purposes. When the frame is in normal use the dofling. member hangs down entirely out of the way.

It will be observed that applicants construction of the frame andparticularly of the rail permits unobstructed access to the spindles for the purpose ofreplacing slack .or broken bands, for oiling and other purposes, and if for any reason it is desired to get access between the spindles when. the

frame is running, any one of the separator blades may be dropped without disturbing the others and may afterward be restored to operative position. The hollow rail forms a large oil reservoir requiring but very-infrequent replenishment and obviates the necessity of oiling each individual pivot from time to time.
